Description (last modified by Bruno Cornec)

I'm having an issue with my mondorestore'ed VM failing to boot after the post-mondorestore reboot. I believe the bootloader (GRUB2) is not being setup correctly by mondorestore.

I've attached mondorestore.log, and I have 3 areas of concern: 1.

INFO: Found Device /dev/vda has a MBR partition type partition table format type on /dev/vda
DBG2: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1539: partition_device('/dev/vda', 1, 0, 'xfs', 1048576) --- starting

DBG1: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1625: Failed to create partition 1 on /dev/vda; sending 'Enter'...

What would cause this?

2.

DBG2: [Main] ../src/mondorestore/mondo-rstr-tools.c->run_grub#1476: mr-grub /dev/vda /tmp/mountlist.txt
Now I'll use grub-install
Launching: chroot /mnt/RESTORING grub-install /dev/vda
chroot: can't execute 'grub-install': No such file or directory
grub-install returned 127
Now I'll use grub2-install
Installing for i386-pc platform.
grub2-install: error: cannot find a GRUB drive for /dev/vda1.  Check your device.map.
grub2-install returned 1

The device.map file has "dev/vda". I’ve also tried manually changing device.map to “/dev/vda1”, but I still see the same error. Any ideas why this might be occurring?

3.

Trying a hack
Checking usr/lib/grub/i386-pc
Cannot find BOOTPATHNAME
.............Cool.
	device (hd0) /dev/vda
	
	root (hd0,0)
	setup (hd0)
	quit 
chroot: can't execute 'grub': No such file or directory
Hack returned res=0

This is a bug in try_grub_hack() of mr-grub. If grub can't be found, the function returns a false positive.
